Classification of F-box proteins in soybean based on C-terminal domains. The F-box proteins were classified into nine subfamilies according to their C-terminal domains. FBU: F-box proteins with unknown C-terminal domains; FBL: those with C-terminal leucine-rich repeats (LRR) domains; FBK: those with C-terminal Kelch domains; FBA: those with C-terminal F-box-associated domains; FBD: those with C-terminal F-box domains; FBT: those with C-terminal tubby (TUB) domains; FBP: those with phloem protein 2 (PP2) domains; FBW: those with WD40 domains; FBO: those with other known domains or with more than one C-terminal domains. The composition of the FBO subfamily is further expanded and represented by the second pie chart. The number after the comma represents the number of F-box proteins in that group. NAD: nicotinamide adenine dinucleotide; DUF295: domain of unknown functions 295; FIST: F-box and intracellular signal transduction; PAS_9: Per-ARNT-Sim 9; LysM: Lys motif; Arm: armadillo repeats; Herpes_UL: herpes virus long unique region; zf-MYND: MYND type zinc finger; MYND: myeloid, Nervy, and DEAF-1, deformed epidermal autoregulatory factor 1; SnoaL: nogalonic acid methyl ester cyclase from S. nogalater. SNF2_N: SNF2 family N-terminal domain; Prenylcys_lyase: prenylcysteine lyase.
